1 Samuel 22
After David escaped Saul and fled from Gath, he was told by the prophet Gad to return to Judah. When Saul heard of his arrival, he accused his officers of conspiring against him. Doeg was among Saul's men and told him that Ahimelech the priest had provided David with food and the sword of Goliath. Saul ordered the death of Ahimelech and all the priests with him and their families. Saul's men refused, but "Doeg the edomite turned on them and killed them, eighty-five priests in all, still wearing their priestly garments.. and killed the priests' families--men, women, children, babies, and cattle, donkey, sheep, and goats." Only Abiathar, one of the sons of Ahimelech escaped and told David what had happened.
